ATTACHMENT FOR CHAIRS. i

Specification of Letters Patent.

Patented July 4,1916.

Application filed November 23, 1914. Serial No. 873,565.

To all whom it may concern:

Be it known that I, FRANK OLSON, a citizen of the United States,residing at WVausa, in the county of Knox and State of Nebraska, haveinvented certain new and useful Improvements in Attachments for Chairs;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in attachments forchairs, and has for its principal object to provide a chair attachmentwhich materially increases the comfort of the article.

Another object of the invention is to provide a device which will holdthe back of the chair in Various adjusted positions to enable the userto recline or sit straight at his desire.

Still another object of the invention is to provide a device whicheffectively forms a stop for the back to prevent the same from goingpast a predetermined limit.

lVith these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which,

Figure 1 is a side view of a. chair showing this attachment as it wouldappear when applied thereto, Fig. 2 is an enlarged side view of theattachment, and Fig. 3 is a top plan view of Fig. 2.

Referring now to the drawings by characters of reference, the numeral 1designates as an entirety a chair provided with the usual bottom 2, arms3, and hinged back 4. This back a is hingedly secured to the bottom asat 5 and is designed to permit the user apertureis spaced slightlyinwardly from the terminal of the body and the extension 12 is designedto project partially into the.

opening through the coil spring. A suitable notch 18 is formed in thebody 11 on its under side, and this notch is inclined upwardly andrearwardly as clearly shown in Fig. 2. A similar notch 14 is formed at apoint slightly in the rear of the notch 13 and this notch forms thetongue 15 which extends downwardly as at 16 and forms a stop to preventthe device from passing a predetermined limit. It will be noted that thewalls of the notches 13 and 14 are inclined rearwardly and the bottomwalls thereof are inclined upwardly toward the forward end of thedevice, and it will thus be seen that the back of the chair will beprevented from becoming accidentally displaced after the same has beenadjusted to the desired position.

From the foregoing it will be apparent that the hooked end S of thespring is con nected as at 17 to the arms 3 of the chair while the wallsof the notches 13 and 14 are arranged to engage the pin 18 carried bythe chair back. After the user has adjusted the back to the desiredposition it will be apparent that he may lean back against the backof'the chair and due to the fact that the spring 7 is interposed betweenthe back and the arms, it will be evident that the back will giveslightly thus making a much more comfortable reclining chair which maybe adjusted to different positions.

WVhile in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the invention as defined in the appendedclaim.

What is claimed is:

The combination with a chair having an of the contractile type locatedin rear of the arm rest and having one end secured to the arm rest andhaving its opposite end extending in the direction of the-back andterminally formed to provide a hook, a plate located in rear of thespring and having an opening for the reception of the hook on theadjacent end of the spring, and extensions formed on the forward end ofthe arm rest and a reclining back, a coil spring plate and extendinginto the interior of the In testimony whereof I affix my signaturespring, a pin carried byfthe chair back, the in presence of twoWitnesses.
